Final Thoughts and Conclusions

Seasonic has once again taken a Great power supply and made it even better. The enhancements made to the X-Series 650/750/850W power supplies translate to excellent performance, high efficiency and the ability to operate in silent-fanless mode at lower power levels.  Throw in a 7-year warranty, a good assortment of all modular cables, really tight voltage regulation, clean DC outputs and you have one very good power supply!

The Seasonic Gold Series X-750 power supply is currently selling for $139.99 USD (, January 2013).
